目前的异形显示屏的生产,主要是对普通液晶显示屏中的不良品进行切割而获得。如图1所示,该液晶显示屏是不良品,其上部为显示效果不良区域110,下部为显示效果正常区域120。切割掉上部的不良区域,那么留下的正常区域,如图2所示,即可形成一个宽长比例非常大的异形显示屏。The current production of shaped displays is mainly obtained by cutting defective products in ordinary liquid crystal displays. As shown in FIG. 1, the liquid crystal display panel is a defective product, and an upper portion thereof is a display effect defective region 110, and a lower portion is a display effect normal region 120. Cut off the bad area of the upper part, then the normal area left, as shown in Figure 2, can form a special-shaped display with a very large aspect ratio.
但是,市场对异形显示屏的需求量越来越大,而液晶显示屏生产厂商的良品率却在逐步提高,所以仅靠上述方式生产的异形显示屏已经难以满足市场的需求。如果对品质合格的液晶显示屏进行切割,虽然能实现异形显示屏的大批量生产,但是其对生产资源的浪费太大,生产成本太高。因此,现有技术中难以在低成本的前提下,实现异形显示屏的大批量生产。However, the demand for special-shaped display screens is increasing, and the yield of liquid crystal display manufacturers is gradually increasing. Therefore, the special-shaped display screens produced by the above-mentioned methods are difficult to meet the market demand. If the quality of the liquid crystal display is cut, although the mass production of the special-shaped display can be realized, the waste of production resources is too large, and the production cost is too high. Therefore, in the prior art, it is difficult to realize mass production of a special-shaped display screen under the premise of low cost.

将上述像素单元结构应用于横向长度非常大,纵向长度非常小的异形显示屏时,因为该异形显示屏纵向的像素单元的数量很少,所以所需的数据线的数量并不多;又因为该异形显示屏横向的像素单元的数量很多,所以每条数据线也能够控制很多的子像素。因此, 采用本发明提供的像素单元结构,能够大幅减少异形显示屏中数据线的数量,并且也使每一条数据线都能控制尽可能多的子像素,从而能够方便的直接生产异形显示屏,而不依赖于切割不良品的生产方式,实现了低成本的异形显示屏的大批量生产。When the above pixel unit structure is applied to a special-shaped display screen having a very large lateral length and a very small longitudinal length, since the number of pixel units in the longitudinal direction of the shaped display screen is small, the number of required data lines is not large; The shaped display has a large number of pixel units in the lateral direction, so each data line can also control a large number of sub-pixels.

It should be noted that the various embodiments of the present invention and the various features of the various embodiments may be combined with each other, and the technical solutions formed are all within the scope of the present invention.
本发明实施例提供一种异形显示屏的像素单元结构,该像素单元结构三个子像素,每个子像素中包括薄膜晶体管。三个子像素中的薄膜晶体管的栅极连接同一条扫描线;三个子像素中的薄膜晶体管的源极分别连接三条数据线,且三条数据线沿纵向排列。Embodiments of the present invention provide a pixel unit structure of a heterogeneous display screen, the pixel unit having three sub-pixels, each of which includes a thin film transistor. The gates of the thin film transistors of the three sub-pixels are connected to the same scan line; the sources of the thin film transistors of the three sub-pixels are respectively connected to three data lines, and the three data lines are arranged in the longitudinal direction.
实施例一:Embodiment 1:
如图3所示,本实施例提供的像素单元结构包括沿纵向排列的三个子像素21、22、23,每个子像素中均设置有包括薄膜晶体管T。其中,三个子像素21、22、23中的薄膜晶体管T的栅极连接同一条扫描线G,并且扫描线G顺次连接至三个子像素21、22、23 中的薄膜晶体管T的栅极;三个子像素21、22、23中的薄膜晶体管T的源极分别连接三条数据线D。本实施例中,三个子像素21、22、23分别为红色子像素、绿色子像素和蓝色子像素。As shown in FIG. 3, the pixel unit structure provided in this embodiment includes three sub-pixels 21, 22, and 23 arranged in the longitudinal direction, and each of the sub-pixels is provided with a thin film transistor T. The gates of the thin film transistors T of the three sub-pixels 21, 22, 23 are connected to the same scanning line G, and the scanning lines G are sequentially connected to the three sub-pixels 21, 22, 23 The gate of the thin film transistor T; the source of the thin film transistor T of the three sub-pixels 21, 22, 23 is connected to three data lines D, respectively. In this embodiment, the three sub-pixels 21, 22, and 23 are a red sub-pixel, a green sub-pixel, and a blue sub-pixel, respectively.
进一步的是,每个子像素中还包括像素电极和公共电极,像素电极与薄膜晶体管T的漏极连接,且像素电极与公共电极之间形成液晶电容Clc。每个子像素中还包括公共电极线COM,像素电极与公共电极线之间形成存储电容Cst。Further, each of the sub-pixels further includes a pixel electrode and a common electrode, the pixel electrode is connected to the drain of the thin film transistor T, and a liquid crystal capacitor Clc is formed between the pixel electrode and the common electrode. A common electrode line COM is further included in each sub-pixel, and a storage capacitor Cst is formed between the pixel electrode and the common electrode line.
另一方面,本发明实施例还提供一种异形显示屏。如图4所示,本发明实施例提供的异形显示屏的横向长度大于纵向长度,也就是宽长比例较大的异形显示屏。In another aspect, an embodiment of the present invention further provides a special-shaped display screen. As shown in FIG. 4, the lateral display length of the special-shaped display screen provided by the embodiment of the present invention is greater than the longitudinal length, that is, the special-shaped display screen having a large aspect ratio.
该异形显示屏包括阵列式排布的若干个像素单元20,且每个像素单元均具有上述实施例提供的像素单元结构,即三个子像素沿纵向排列,且三个子像素对应的三条数据线也沿纵向排列。采用此种像素单元结构之后,该异形显示屏所需的数据线的总数等于纵向像素单元总数的三倍;并且每条数据线能够控制整整一行子像素。The shaped display screen includes a plurality of pixel units 20 arranged in an array, and each of the pixel units has the pixel unit structure provided by the above embodiments, that is, three sub-pixels are arranged in the longitudinal direction, and three data lines corresponding to the three sub-pixels are also Arranged in the longitudinal direction. With such a pixel cell structure, the total number of data lines required for the shaped display screen is equal to three times the total number of vertical pixel cells; and each data line can control a whole row of sub-pixels.
因为该异形显示屏纵向的像素单元的数量很少,所以所需的数据线的数量并不多;又因为该异形显示屏横向的像素单元的数量很多,所以每条数据线也能够控制很多的子像素。Because the number of pixel units in the longitudinal direction of the shaped display screen is small, the number of required data lines is not large; and because the number of pixel units in the lateral direction of the shaped display screen is large, each data line can also control a lot of Subpixel.
而现有的异形显示屏中,如图2所示,每个像素单元10是由横向排列的三个子像素11、12、13构成,且三个子像素11、12、13连接同一条扫描线,三个子像素11、12、13分别连接三条数据线。因此,现有的异形显示屏所需的数据线的总数等于横向像素单元总数的三倍,每条数据线能够控制一整列子像素。因为异形显示屏横向的像素单元的数量很多,纵向的像素单元的数量很少,所以所需的数据线的数量非常多,但每条数据线控制的子像素的数量非常少,导致数据线的使用效率很低,造成数据线资源的浪费。In the conventional heterogeneous display screen, as shown in FIG. 2, each pixel unit 10 is composed of three sub-pixels 11, 12, 13 arranged in a lateral direction, and three sub-pixels 11, 12, 13 are connected to the same scanning line. The three sub-pixels 11, 12, 13 are respectively connected to three data lines. Therefore, the total number of data lines required for the existing shaped display screen is equal to three times the total number of horizontal pixel units, and each data line can control an entire column of sub-pixels. Because the number of pixel units in the horizontal direction of the shaped display screen is large, the number of vertical pixel units is small, so the number of required data lines is very large, but the number of sub-pixels controlled by each data line is very small, resulting in data lines. The use efficiency is very low, resulting in waste of data line resources.
此外,现有的异形显示屏中由于数据线的数量非常多,所以也需要更多、更复杂的数据驱动电路。从图2中可以看出,在该异形显示屏的下侧,数据处理芯片130连接有两个数据驱动电路板140。In addition, in the existing shaped display screen, since the number of data lines is very large, more and more complicated data driving circuits are also needed. As can be seen from FIG. 2, on the lower side of the shaped display screen, the data processing chip 130 is connected to two data driving circuit boards 140.
另一方面,现有的异形显示屏中,每条扫描线用于控制一整行子像素。因为横向的像素单元的数量很多,所以每条扫描线控制的子像素的数量也很低,且扫描线的长度也很大,则很容易因为扫描线的延时造成部分子像素充电不足,而影响异形显示屏的显示效果。On the other hand, in the conventional shaped display, each scan line is used to control an entire row of sub-pixels. Because the number of horizontal pixel units is large, the number of sub-pixels controlled by each scan line is also low, and the length of the scan lines is also large, so it is easy to partially charge the sub-pixels due to the delay of the scan lines. Affects the display of the shaped display.
相比于现有技术,本发明实施例提供的异形显示屏,由于采用了本实施例提供的像素单元结构,能够大幅减少异形显示屏中数据线的数量,并且也使每一条数据线都能控制尽可能多的子像素,从而显著提高了数据线的使用效率,也避免了数据线资源的浪费。因此, 采用本发明实施例提供的技术方案,能够方便的直接生产异形显示屏,而不依赖于切割不良品的生产方式,实现了低成本的异形显示屏的大批量生产。Compared with the prior art, the special-shaped display screen provided by the embodiment of the present invention can greatly reduce the number of data lines in the special-shaped display screen by using the pixel unit structure provided by the embodiment, and also enables each data line to be Control as many sub-pixels as possible, which significantly improves the efficiency of data line usage and avoids waste of data line resources. Therefore, By adopting the technical solution provided by the embodiment of the invention, the special-shaped display screen can be directly produced conveniently, without relying on the production mode of the defective product, and the mass production of the low-cost special-shaped display screen is realized.
进一步的是,本发明实施例提供的异形显示屏包括阵列基板和彩膜基板,以及填充于阵列基板与彩膜基板之间的液晶层。作为一个优选方案,栅极驱动电路可以采用阵列基板行驱动(Gate Driver On Array,简称GOA)方式设置于阵列基板上。利用GOA技术将栅极驱动电路制作在阵列基板上,从而可以运用阵列基板的原有制程将栅极驱动电路制作在阵列基板的板边区域,以替代原有的外接驱动芯片。因此,GOA技术能够省去驱动芯片的绑定工序,提升产能并降低产品成本,而且可以减小显示装置的边框宽度。Further, the shaped display screen provided by the embodiment of the invention includes an array substrate and a color filter substrate, and a liquid crystal layer filled between the array substrate and the color filter substrate. As a preferred solution, the gate driving circuit can be disposed on the array substrate by using a Gate Driver On Array (GOA). The gate driving circuit is fabricated on the array substrate by using the GOA technology, so that the gate driving circuit can be fabricated on the edge region of the array substrate by using the original process of the array substrate to replace the original external driving chip. Therefore, the GOA technology can eliminate the binding process of the driver chip, increase the productivity and reduce the product cost, and can reduce the frame width of the display device.
另外,因为本发明实施例中,异形显示屏在纵向的像素单元的数量很少,所以每条扫描线所控制的子像素的数量也很少,而且扫描线的长度很短,从而能够避免扫描线的延时造成部分子像素充电不足的现象发生,保证了异形显示屏的显示效果。In addition, in the embodiment of the present invention, the number of pixel units in the vertical direction of the shaped display screen is small, so the number of sub-pixels controlled by each scanning line is small, and the length of the scanning line is short, thereby avoiding scanning. The delay of the line causes the phenomenon that some sub-pixels are insufficiently charged, which ensures the display effect of the special-shaped display.
如图4所示,本实施例中,在阵列基板的一侧设置有数据驱动电路板30,用于向各个像素单元输出数据信号,该数据驱动电路30板优选为设置在阵列基板的短边一侧。As shown in FIG. 4, in this embodiment, a data driving circuit board 30 is disposed on one side of the array substrate for outputting data signals to the respective pixel units, and the data driving circuit 30 board is preferably disposed on the short side of the array substrate. One side.
因为本发明实施例提供的异形显示屏所需的数据线的数量非常少,所以只需设置一个数据驱动电路板30就能够满足数据信号的输出。相比于现有技术,本发明实施例还减少了电路板的使用数量,降低了电路板的总体面积,从而节约了器件的使用量,降低了异形显示屏的生产成本。Because the number of data lines required for the shaped display screen provided by the embodiment of the present invention is very small, only one data driving circuit board 30 is required to satisfy the output of the data signal. Compared with the prior art, the embodiment of the invention also reduces the number of used boards, reduces the overall area of the board, thereby saving the usage of the device and reducing the production cost of the special-shaped display.

With such a pixel cell structure, the total number of data lines required for the shaped display screen is equal to three times the total number of vertical pixel cells; and each data line can control a whole row of pixel cells.
因为该异形显示屏纵向的像素单元的数量很少,所以所需的数据线的数量并不多;又因为该异形显示屏横向的像素单元的数量很多,所以每条数据线也能够控制很多的子像素。Because the number of pixel units in the longitudinal direction of the shaped display screen is small, the number of required data lines is not large; and because the number of pixel units in the lateral direction of the shaped display screen is large, each data line can also control a lot of Subpixel.

另外,因为本发明实施例中,异形显示屏在纵向的像素单元的数量很少,所以每条扫描线所控制的子像素的数量也很少,而且扫描线的长度很短,从而能够避免扫描线的延时造成部分子像素充电不足的现象发生,保证了异形显示屏的显示效果。In addition, in the embodiment of the present invention, the number of pixel units in the vertical direction of the shaped display screen is small, so the number of sub-pixels controlled by each scanning line is small, and the length of the scanning line is short, thereby avoiding scanning.
